Leybold develops vacuum solution for sustainable beer bottling

Oil-free vacuum reduces costs and ensures a high level of hygiene

"The BBVS (Beer Bottling Vacuum System) comes as an all-in-one turnkey solution to replace the old liquid ring pump technology. It includes a separator tank with an automatic operated draining vessel to stop foam and liquid carried over from the filler via the gas flow. The DRYVAC dry screw vacuum pump provides deep constant vacuum levels, while an electrical cabinet with PLC controls the entire system

The classic glass beer bottle offers T numerous advantages for producers and consumers compared to other types of containers. In addition to a fresh taste and protection from external contaminants, the bottle design communicates the brand image and contributes to the enjoyment of the beverage. With this in mind, it's no coincidence that in Germany alone, there are currently several billion glass bottles from various breweries in circulation.

Quality risk due to oxygen ingress

In order to preserve these benefits, specific technical considerations must be taken into account when filling glass bottles, as beer is especially sensitive to oxygen. If too much oxygen enters the bottle during the filling process, adverse chemical reaction can occur. This results in a loss of quality in terms of taste, color and shelf life. In order to limit the amount of residual oxygen, the bottling process takes place under controlled vacuum conditions.
